Schneider Electric BMXDDM3202K Modicon X80 16 DI/16 DO 24V DC Discrete I/O Module

The Schneider Electric BMXDDM3202K is a Modicon X80 discrete mixed I/O module with 16 transistor inputs and 16 transistor outputs at 24 V DC, built for Modicon M340 and M580 PAC racks. Each output channel switches 0.125 A (3.2 A per module), and the module carries an IP20 rating with a 430,000-hour MTBF.

Selection Notes

Pick the BMXDDM3202K over the 8-channel variant when a rack slot needs to double the point count within the same footprint — its 3.2 A module current budget is split across 16 outputs (0.125 A each), so it suits distributed low-current loads like PLC-driven indicator banks rather than a few higher-draw actuators. Paralleling up to 3 outputs extends the available current per point when a single channel's 0.125 A is insufficient. The module's voltage-detection thresholds — below 14 V DC flags a sensor or pre-actuator fault, above 18 V DC confirms OK — let the PAC diagnose a broken input wire or a blown output fuse without extra wiring, and the 0.5 A external fast-blow fuse specified per input group protects the module itself from field-side short circuits.
